http://askubuntu.com –
Basically as is the title how do you install Myunity on 12.10. I've tried adding the repository ppa:myunity/ppa and doing the whole,
sudo add-apt-repository ppa:myunity/ppa
sudo apt-get update
sudo apt-get install myunity
At which point I got the error:
W: Failed to fetch http://ppa.launchpad.net/myunity/ppa/ubuntu/dists/quantal/main/binary-i3... 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.
